OTTO BAR/TEL, OF NEW YORK, NJY.

TORCH.

Y '0 all whom it may concern Be it known that I, O'rro BARTEL, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented new and useful Improvements in Torches, of which the following is a specification. My invention consists of a new and im proved torch in which alcohol is used principally as a fuel, although any other suitable material may be used.

The torch can be made at a very low cost with few parts and is simple in construction and its mode of operation.

As some inflammable fluids particularly alcohol require a complicated burner in order for the fluid to be vaporized, I have constructed a torch with a simple and cheaply constructed burner. My device consists essentially of two tanks one to hold the fluid of which the vapor is made and another tank holding the fluid which supplies the heating lamp. These tanks are connected in such a way that their relative position to each other remains the same when the torch is in operation. The connection can be made in any suitable manner but should preferably provide means of separation of the tanks for the purpose of filling and also for the purpose of using the lamp as a lighter for the vapor.

In the accompanying'drawings: Figure l is a sectional view of a torch made ll] accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a sectional view of a modification. Fig. at is a side clevation of a torch showing a connection between t-he heating lamp and the holding tank. y

In this drawing the numeral 1 designates the tank which holds the fluid adapted to be vaporized. Thistank has a screw cover 2 which lits into a screw thread 3 formed on the interior of the tank. A washer #forms a tight closure between the cover and tank.

'Sccured to the back of the tank is a handle 4- whcreby the device may be carried. The interior of the tank 1 contains a packing material 5 such as cr-ltOn or any other absorbent material. The front of the tank is provided with a threaded opening having a flange (i. A wick tube 8 screws into the threaded opening and a washer 7 gives tight Specification of Letters Patent.

Serial No. 617,807.

A burner tube 13 projects from the wick tube and it has an open end for the flame to issue. A wick 12 extends from the wick tube into the tank. At the end of the wick tube is situated a wall or diaphragm 10 having a small central opening 11 for the vapor 'to pass through. Underneath the wick tube 8 there is a small lamp having a supplemental tank 14 with a threaded opening 16 which is adapted to reeeive a screw cover15. A washer 17 is interposed between the cover and the tank to prevent leakage. A wick tube.18 projects from the screw cover 15 and a wick 19 extends from the tube into the tank. The tank 14 rests in and is held in position in a socket 21 which may be made integral with the base 22.

In the modification shown in Fig. 1 the lamp tank 14 is connected to the vapor tank 1 by a U shaped connection 24 fitted into a bracket 23 secured on the tank 14. The

closure to the parts.

wick contained in the su plemental lamp tank 14 is lighted and p aced in position which brings the flame under the burner tube 8. The wick inside of the burner tube, being saturated with the fluid becomes heated and the fluid va-porizes and escapes through the small opening 11 into the burner tube. The flame of the lamp keeps the burner tube continuously heated and thus a continued stream of vapor is produced which when lighted at. the end of the burner tube forms a blue flame of intense heat.

In the modification Fig. 3, the lamp tank is placed directly under the fuel tank. The flame from the wick 18 may be regulated by means of a sleeve 25 which can be adjusted up or down on the tube and thus cover more or less of the wick as indicated in Fig. 3. A burner 26 for the lamp may be used, the burner having an opening which is closed by a packing spilled when the torch is tilted and confines the size of the flame in accordance with the opening in the burner.
